AIIMS 2019 Zoology Somaclonal Variation Assertion Reason Question
Assertion: Somaclonal variations produce slight differences in plant Reason: In bacteria, transcription and translation occurs in cytoplasm
If both assertion and reason are true and reason is the correct explanation of assertion.
If both assertion and reason are true but reason is not the correct explanation of assertion.
If assertion is true but reason is false
If both assertion and reason are false.
Correct Answer
Detailed Explanation
Option C is correct because the assertion that somaclonal variations produce slight differences in plants is true; these variations arise from genetic changes during tissue culture. However, the reason provided is false; in bacteria, transcription (the synthesis of RNA from DNA) and translation (the synthesis of proteins from RNA) occur simultaneously in the cytoplasm, not as a reason for somaclonal variation. Option A is incorrect because the reason does not explain the assertion, while option B is incorrect as it suggests both statements are true but fails to connect them. Option D is incorrect because the assertion is indeed true.
